The NRT-XS is a small and compact emergency call device for elevators. It is available in three versions to allow either a hidden installation in the panel, a built-in installation (with a stainless steel-panel) or a surface-mounted installation. In addition to the integrated elements “microphone”, “speaker” and “status display” (in accordance with EN81-70), the option to operate up to nine devices on one telephone line is one of the outstanding features of the NRT-XS. The NRT XS tests the microphone, speaker and telephone line automatically. It also reports problems and initiates actions to ensure a safe operation of the elevator at any time. The emergency telephone NRT-XS is ideally suited for the use in elevators for passenger and freight.
